Buckingham Palace Releases a Sweet New Portrait of Queen Elizabeth with Prince Philip

The romance between Queen Elizabeth II and Prince Philip, Duke of Edinburgh, still gives us butterflies—even after 68 years.

In the aftermath of the beloved monarch's 90th birthday—which took place earlier this year on April 21—Buckingham Palace released the last from a set of official portraits of the queen taken by Annie Leibovitz to commemorate the milestone.

The earlier photos featured the queen at Windsor Castle, with her dogs, and with her adorable brood of growing descendants. The last and final one is a portrait (below) of the original royal couple, which was released today, Philip's 95th birthday. The sweet photo shows the longtime loves smiling ever-so-slightly and looking as cute.

In this undated photo released by Buckingham Palace on Friday, June 10, 2016, Britain's Queen Elizabeth II, left and Prince Philip, the Duke of Edinburgh pose for a photograph to mark the Queen's 90th birthday, in Windsor, England. The queen, Britain’s oldest and longest-reigning monarch, turned 90 on April 21. She usually celebrates her birthday privately, but this year’s milestone served as the jumping off point for weeks of celebrations.

Queen Elizabeth is officially the longest-serving British monarch (64 years and counting on the throne) in history and her 68-year marriage to Philip makes them the longest-married monarch-and-consort in British history. No small feat! Weeks of celebrations culminate this weekend with the annual Trooping the Colour parade and pageant on Saturday, followed by the largest ever street party on Sunday at The Mall in St James's Park.
